When opening the schematics, all the custom symbols are replaced by big squares labelled with "??".

⇒ either keep the library folder where it is and add the custom symbol libraries into the project, taking care of expressing the pathes relative to the project directory

⇒ or move the library folder into the kicad project and then add these libraries into the project (in this case Kicad use relative pathes without being told to) ⇒ see PR #2

Thank you for the time and effort you've put in to developing something amazing!

I built Gerbers and placed an order for some boards (with PCBWay) and they informed me that the pad-to-pad clearance for the FPGA was 0.02mm below their minimum tolerance for any soldermask color other than green. After checking the Xilinx spec sheet at https://www.xilinx.com/support/documents/package_specs/tq144.pdf it looks like the maximum pin width is 0.27mm, whereas the default KiCad package is 0.30mm.

I made a new package based with 0.27mm pins tweaked the wider track widths connecting to it, as well as made sure the smaller tracks were centered in the pads, and then built new Gerbers and submitted them. Hopefully they pass PCBWay's DRC with those changes. I'll post an update here if so or if I end up needing to do more.

My changes are at https://github.com/DominoTree/DFB if you'd like to swap footprints or anything. I used KiCad 6 and just modified the footprint on the PCB itself - if you want to use it and have trouble let me know and I'll re-generate it in KiCad 5 and save it as its own footprint. This could be a quick way to make these boards easier and cheaper for more folks to have manufactured.

Thanks again, and feel free to let me know if you have any questions or if there's anything I can help with!

Trying to open the project in Kicad6, it seems that the standards symbols Jumper_NO_Small and Jumper_NC_Small are not there anymore.

They should be extracted into a custom library to be added and used by the project

Hello,

Working on fixing the portability of the kicad project (see also PR #2 ).

There is a reference to a footprint Jumper:SolderJumper-2_P1.3mm_Bridged_RoundedPad1.0x1.5mm_DAVID that seems to me a duplicate from the builtin Jumper:SolderJumper-2_P1.3mm_Bridged_RoundedPad1.0x1.5mm, but as it is located in the same system library, it is outside this repository.

What is different in your custom reference ? Is it possible to go back to the standard footprint ? Otherwise, it would be good that you include your custom version into the local footprint library that you made.
